This will show up on post icon on the right side, for example if you click my "Contact" bubble you will see a menu which has steam profile as an option with a "world" icon. By clicking that, you will be redirected to the user profile where you can see the link.

WARNING: It can be any website, just so you don't randomly click it at work and be redirected at meatspin or something similar (there's actually no way to show the link before hand).

More safe way to check this is to open their profile and you will see the link under "Contact info".

This replaces the standard Website profile option, but I don't think anyone uses it anyways.

1. Click your user name to get to your profile page, select "Profile" from the menu which should open.

2. Click on "Edit profile", your profile settings will open. Your "own" URL address will show up here too, and you can actually edit it if you want to change it.

3. This is where your steam profile URL is. You can change the last bit to what ever which is not already taken, if you want to.

4. Click privacy settings. This is where you select what you share to others. Your profile has to be set as "Public" if you want to allow other players invite you to their friends this way. It also means that everyone can check out your profile and see how many hours you have played Blood Bowl 2 (or any other steam products) or if you are currently online etc.

You can consider this to be something you want to keep private, so you may not want to share your steam profile with the whole world. Consider it as a face book page which is open to everyone. I personally do not care.

I decided to create us a Steam usergroup, this way you don't have to share your profile to whole world if you do not want to but can still share easier communication with other Steam users. This doesn't mean you have to or even should to apply, but I will send invite to everyone who puts their steam profile in our forums. Feel free to accept or decline as you see fit.
